Sure it's not 2000? Very common to see the P2000 code and it would probably be soot on the oxygen sensor.

does anyone know the code P3000

How did you determine it is P3000?

Did you use a code reader?

If so, what kind?

Did you use the key method?

after 3 hours and $165 and a whole lot of incompetence at the dealer (last cel), I went to a mechanic friend who has one of those diagnostic hand-held tools. The code was P3000
I did look at the sticky here -thanks by the way- but there is nothing close P3000

I don't know the kind of code reader he used
